all identical except colour. 8 blue, 4 red

What if the question was, no. of ways you can form a ring with the balls?

The balls are identical in size. My answer was wrong, anyhow. WIll give a shot soon.

Are the balls identical? If not, i think this should work, though not sure.

It appeared to me too that a,b,c all cant be real. If we could find the value of a*b*c, then the problem could be done. Can you please provide a link for newton raphson method (some easy explanation )

Sorry for such delay. Here goes - 'Going, Going, Gone....'

I am getting

Any Hint for me?

Can you share the code?

Did we write our decimals out of order? Because I got 11.05727... The difference is small though so I will still give you best answer. I did the same way as you have done, its just that i thought if i am right, writing till only 3-4 decimal places would be sufficient.. you got .0527 where i got .0572. So i wasn't sure if you used a different strategy or inverted your numbers Whoops, sorry. I mistyped.

Agree with Superprismatic. I think u have counted (1, 2*10^250-1) also.

Ok thanks. I didnt realise expected value may be a fraction.
